  ABSTRACT
  In the present paper, the Authors describe a new species of the genus Ferussacia Risso, 1826 (Gastropoda Stylommatophora Ferussaciidae) from western Sicily (Italy): F. antonini n. sp. It is very different, at first sight, from F. folliculum (Schröter, 1784), the only other species very widespread in Sicily, mainly due to the shape of the shell formed by 5 whorls with the last whorl comprising 2/3 of the entire shell height. Further information on the biology of this new species and the taxonomy and anatomy of Ferussacia species living in Sicily are provided.

  ABSTRACT
  Malacological surveys in the limestone massifs west of Palermo (Carini, NW Sicily), revealed the presence of a new species of Aciculidae: Acicula occidentalis n. sp. (Gastropoda Architaenioglossa Aciculidae). Diagnostic traits are: the high number of axial irregularly distributed grooves, the sub-rectangular to pyriform aperture and the larger size compared to other Acicula taxa known for Sicily. Acicula occidentalis n. sp. seems to be restricted to the mountains west of Palermo, until now known only to the eastern slopes of Montagna Longa (Carini).
